Skill acquisition and the timing of natal dispersal in the white-throated magpie-jay, Calocitta formosa

Article Abstract:

Offspring of white-throated magpie-jay, Calocitta formosa, exhibit an increased skill acquisition rate on association with parents. Male natal dispersal occurs once feeding skill maturity is attained and with the onset of breeding season while females remain as helpers long after skills have been learned. Larger groups show earlier dispersion than smaller groups. Magpie-jays provide food to offspring during the first three months before fledging.

Parentage and reproductive success in the white-throated magpie-jay, Calocitta formosa, a co-operative breeder with female helpers

Article Abstract:

A study was conducted to investigate parentage in a Costa-Rican population of white-throated magpie-jays, a co-operative breeder in the tropical dry forest of Central America. The results showed that a more complex combination of co-operative and parasitic behaviors were suggested instead of simple classification of white-throated magpie-jays, as co-operative breeders.

Parents increase their parental effort when aided by helpers in a cooperatively breeding bird

Article Abstract:

Parental behavior in cooperatively breeding species of birds is analyzed. Changes in the parental effort to feed their young when aided by helpers are studied in the case of Cyanopica cyanus, the azure-winged magpie.
